2007-08-21Cleanup: remove linux/moduleparam.h from drivers/media filesMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Since at least kernel 2.6.12-rc2, module.h includes moduleparm.h. This patch removes all occurences of moduleparm.h from drivers/media files. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-08-17Get rid of an ill-behaved msleep in i2c writeMauro Carvalho Chehab
From: Jonathan Corbet <corbet@lwn.net> Configuring the OLPC camera requires something over 150 register writes. Unfortunately, querying the CAFE i2c controller too soon after a write causes the hardware to flake. The problem had been "solved" with an msleep() call, but, between the number of registers and how msleep() behaves, that resulted in a 3-second delay on camera initialization. Instead, we hand-code a wait for the completion interrupt which avoids reading the status registers.

2007-07-02Fix v4l-dvb backward compatibilityMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Due to several internal API changes on kernel, kernel backward compatibility were lost. Basically, compat.h should be the last include for it to work properly. This patch basically reorders kernel headers to allow backward compat to work fine. Also: Some includes were added after some non-include macros, on old drivers. Better to keep all includes at the beginning of the files. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-05-22Ov7670: reset clkrc in rgb565 modeMauro Carvalho Chehab
From: Jonathan Corbet <corbet@lwn.net> A bug in the ov7670 sensor causes it to introduce noise unless the CLKRC register is rewritten *after* setting the image mode. Naturally, resetting CLKRC in this way will cause other modes to fail. So carefully poke the register only when indicated.

2007-03-255/7 Don't mirror ov7670 images by defaultMauro Carvalho Chehab
From: Jonathan Corbet <corbet@lwn.net> Don't mirror ov7670 images by default The ov7670 sensor driver sets the mirror bit by default, which is not the desired mode. OLPC has been running with this patch for a while. Signed-off-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-27Improve VIDIOC_G_CHIP_IDENT (better diagnostics)Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Simplify the VIDIOC_G_CHIP_IDENT implementation by adding a single common function. The ident can now also return NONE: not found, UNKNOWN: found, but we don't know what chip it is, and AMBIGUOUS: multiple chips were matched so the match values were too general. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-02-24Add support for VIDIOC_G_CHIP_IDENTHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> VIDIOC_G_CHIP_IDENT improves debugging of card problems: it can be used to detect which chips are on the board and based on that information selected register dumps can be made, making it easy to debug complicated media chips containing tens or hundreds of registers. This ioctl replaces the internal VIDIOC_INT_G_CHIP_IDENT ioctl. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> CC: Jonathan Corbet <corbet@lwn.net>

2006-11-04Make ov7670 and cafe_ccic compile at v4l-dvb treeMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Those driver are developed using some stuff from newer kernels. Maybe they may compile with kernels lower than 2.6.19, but upper than 2.6.16. Anyway,since the targeted OLPC hardware is not available yet, IMO, it doesn't make much sense to work on backporting the drivers to kernels lower than kernel 2.6.19.
